* Type housekeeping.Paul Phillips2013-09-181-1/+2
| | | | | | | | | | | Moved ListOfNil somewhere more generally accessible. No reason the compiler should hoard it for itself. Flitted to a few locations with constructs like ".head.head" and ".tail.head" looking for code which could be rewritten. Found some, admittedly not always making use of ListOfNil. Made overdue moves of ConstantType(Constant(true|false|null)) to vals in Definitions.
* Started eliminating modes.Paul Phillips2013-05-111-4/+0
| | | | | | | | | | | | | | Consolidating the scattered typer state in Context, where it's relatively easy to keep an eye on, rather than threaded throughout the typer in sneaky/sticky bitmasks. The general pattern will be what was once an explicitly passed around bit in Mode becomes an implicitly propagated-as-appropriate bit in Context. In this commit: ALTmode becomes context mode "PatternAlternative" STARmode becomes context mode "StarPatterns" SUPERCONSTRmode becomes context mode "SuperInit"

| * Made "mode" into a value class.Paul Phillips2013-01-091-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an obvious place to apply value class goodness and collect some safety/sanity in typing modes. It does show off a challenge in introducing value classes without disruption: there's no way to deprecate the old signature of 'typed', 'adapt', etc. because they erase the same. class Bippy(val x: Int) extends AnyVal class A { @deprecated("Use a bippy") def f(x: Int): Int = 5 def f(x: Bippy): Int = x.x } ./a.scala:5: error: double definition: method f:(x: Bippy)Int and method f:(x: Int)Int at line 4 have same type after erasure: (x: Int)Int An Int => Mode implicit handles most uses, but nothing can be done to avoid breaking anything which e.g. extends Typer and overrides typed.
* | Incorporated Variance value class in Variances.Paul Phillips2013-01-091-0/+3
|/ | | | | No one will ever know what it took for me to refine Variances into its current condition. A LONELY QUEST.

* Hunting down eliminable :: allocations.Paul Phillips2012-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With this commit, the number of :: allocations logged in total after individually compiling each scala file in src/compiler drops from 190,766,642 to 170,679,925. Twenty million fewer colon-colons in the world, it's a start. For some heavily used lists like List(List()) I made vals so we can reuse the same one every time, e.g. val ListOfNil = List(Nil) The modifications in this patch were informed by logging call frequency to List.apply and examining the heaviest users. >> Origins tag 'listApply' logged 3041128 calls from 318 distinguished sources. 1497759 scala.reflect.internal.Definitions$ValueClassDefinitions$class.ScalaValueClasses(Definitions.scala:149) 173737 scala.reflect.internal.Symbols$Symbol.alternatives(Symbols.scala:1525) 148642 scala.tools.nsc.typechecker.SuperAccessors$SuperAccTransformer.transform(SuperAccessors.scala:306) 141676 scala.tools.nsc.transform.SpecializeTypes$$anonfun$scala$tools$nsc$transform$SpecializeTypes$$specializedOn$3.apply(SpecializeTypes.scala:114) 69049 scala.tools.nsc.transform.LazyVals$LazyValues$$anonfun$1.apply(LazyVals.scala:79) 62854 scala.tools.nsc.transform.SpecializeTypes.specializedTypeVars(SpecializeTypes.scala:427) 54781 scala.tools.nsc.typechecker.SuperAccessors$SuperAccTransformer.transform(SuperAccessors.scala:293) 54486 scala.reflect.internal.Symbols$Symbol.newSyntheticValueParams(Symbols.scala:334) 53843 scala.tools.nsc.backend.icode.Opcodes$opcodes$CZJUMP.<init>(Opcodes.scala:562) ... etc.

* There is a lot of housecleaning to be done.Paul Phillips2011-01-291-0/+13
up the stray interpreter files and put them in the interpreter package. Would really love to change the name of that package. Went looking for some consistent divisions of responsibility and consistent naming. Made some progress. There are deprecated versions of most everything I changed so hopefully the carnage will be limited. This isn't completely baked but I just realized I broke the build earlier and this should fix it. I'll keep the oven on. No review.
